30 MPG combined won’t win any hypermiling contests, but for the 2022 Buick Encore GX FWD with its 1.2L 3-cylinder engine, it represents a sensible balance. This isn’t a performance SUV; it’s a comfortable, stylish, and relatively affordable option primarily for urban dwellers, empty nesters, and those simply seeking a manageable footprint with a touch of premium flair. Fuel economy is a consideration, not the single defining factor, in their purchase.

City and Highway performance

The EPA estimates for the Encore GX are quite tightly grouped, reflecting the nature of its powertrain and its expected driving environment. You’ll see 29 MPG in the city and 31 MPG on the highway. The close numbers suggest that the continuously variable transmission (CVT) is doing a decent job of keeping the engine in its sweet spot regardless of speed. However, it also hints that the small engine may have to work relatively hard at higher speeds, limiting the highway fuel economy advantage over city driving. This is not surprising, as the engine is prioritized for smooth low-end torque needed for urban driving rather than sustained high-speed passing power.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2022 Buick Encore GX FWD 1.2L 3-cyl will be $1,450. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s a useful benchmark for comparison, but your actual fuel costs will vary depending on your driving habits, local fuel prices, and the condition of your vehicle. This is just an estimate; if you drive significantly less than 15,000 miles per year, your fuel expenses will be proportionately lower. More aggressive driving or higher local gas prices will inflate that $1,450 figure.

Real-world expectations

While the EPA provides a standardized benchmark, your individual mileage experience may vary. In real-world conditions, you can expect figures that fluctuate around those EPA estimates. City driving with frequent stop-and-go traffic, aggressive acceleration, and heavy reliance on air conditioning will likely yield slightly lower numbers, possibly dipping into the mid-20s MPG range. Conversely, long highway stretches, maintaining a consistent speed, and minimal use of accessories could push the MPG closer to, or perhaps even slightly above, the 31 MPG rating. Achieving the advertised MPG requires a conscious effort to drive efficiently.

How it compares

Compared to other subcompact SUVs, the Encore GX’s fuel economy is competitive but not groundbreaking. For example, the front-wheel drive Nissan Kicks boasts a combined 33 MPG. The previous generation Buick Encore, documented in ENCORE MPG across all years, achieves similar gas mileage though with very different driving dynamics. The Mazda CX-30 with its standard 2.5L engine delivers a combined 26 MPG, a trade-off for noticeably better performance. Even within the Buick lineup, there are variations; explore all Buick fuel economy data to see how the Encore GX stacks up against other models. The typical Encore GX buyer probably isn’t cross-shopping against high-performance or dedicated fuel-sipping machines; they are weighing factors such as size, features, and brand perception. Fuel economy is a factor, of course, but it is balanced with the desire for a comfortable and stylish vehicle.

Tips to maximize efficiency

The Encore GX’s CVT is designed to optimize fuel economy. Avoid aggressive acceleration, as pressing the accelerator pedal hard forces the small engine to work harder and consume more fuel. Smooth, gradual acceleration allows the CVT to efficiently adjust the gear ratio and maintain optimal engine speed.

Tire pressure significantly impacts fuel economy. Ensure your tires are properly inflated to the recommended PSI listed on the driver’s side doorjamb. Underinflated tires create more rolling resistance, forcing the engine to work harder and reducing fuel efficiency. Check your tire pressure regularly, especially during temperature changes.

Excess weight reduces MPG. Remove unnecessary items from the vehicle as extra weight requires more energy to move, negatively impacting mileage. Avoid carrying heavy cargo unless absolutely necessary. Simple actions like emptying the trunk and removing unused roof racks can improve your fuel efficiency.

Plan your trips carefully to avoid traffic congestion. Stop-and-go traffic creates unnecessary fuel consumption. Use navigation apps to find the most efficient routes and avoid peak traffic hours if possible. Combining multiple errands into a single trip also minimizes cold starts, which are less fuel-efficient.

Consider the climate control settings. Using the air conditioning, especially at full blast, places a significant drain on the engine. When possible, use the ventilation system or roll down the windows to keep the cabin cool. For shorter drives, avoid using the AC altogether.
